Improving energy efficiency and reliability of heating networks through the use of multilayer thermal insulation structures

Abstract

Thermal insulation of pipelines is actively used to reduce heat losses in heat supply systems, as well as to reduce the temperature on the utilities surfaces, for safety during daily operation. This method ensures uninterrupted operation of heating systems in the winter, eliminating the risk of the heat carrier freezing and, consequently, their failure. At the moment, the application of effective thermal insulation of heating network equipment and pipelines is of great importance. The lack of a high-quality heat-insulating coating on the pipeline surface leads to significant losses of fund from various level budgets and a decrease in the quality of the heat carrier, that is, its temperature. Special requirements are imposed on thermal insulation materials, according to current regulatory documents, compliance with which is monitored by specialized organizations. The thermophysical indicators study of modern heat-insulating materials of domestic production and their application impact on the efficiency of the heat supply system is an urgent task aimed at improving energy efficiency and reducing energy consumption by reducing heat losses in heating networks pipelines.

Testing heat supply networks for heat losses

“…The target of the tests is to determine the heat losses for various types of routing and design of the pipeline insulation that are specific to the heat network in question. Based on the test results, the insulation condition of the tested pipelines under the specific routing operating conditions is assessed [1][2][3][4]. The tests were performed for the network sections with the routing type and the insulation design is the characteristic of the given network, which facilitates expansion of the test results to the heating network as a whole [5][6][7][8][9].…”
